Economic Forecasts: Too smooth by far?

Will the US and other economies slip into recessions this year? Which economies will decouple from a global slowdown? The authors suggest that the excessive caution shown by private sector forecasters limits the usefulness of their forecasts in answering these questions. Using growth forecasts for 14 major economies from 1990 onwards, they demonstrate that revisions made to forecast are extremely smooth. An implication of this smoothness is that forecasters do not call a recession until fairly late in the year in which the recession occurs. They are also slow to absorb news about developments outside their own economies, limiting the ability of the growth forecasts to predict the extent of decoupling.
